SPECIFICATION forming part of Letters Patent N 0. 694,267, datedFebruary 25, 1902. Application filed August 29, 1901. Serial No. 73,726.(No model.)

To all whom, it may concern.-

Be it known that I, WILHELM GRIESSER, a citizen of the United States,residing at New York city, in the county of New York and State of NewYork, have invented new and useful Improvements in Brewers Vats, ofwhich the following is a specification.

My invention relates to brewers vats and other like wooden storagevessels, the same residing in the construction and means of securing inplace the metallic fittings surrounding the manhole and in the means formounting the door. In this class of inventions it is common to employaround the manhole a metallic frame made up of an inner and an outerring secured to each other and to the staves of which the vessel is madeby bolts extending through said staves and through said rings. Oneimportant objection to this old means of construction is that theopenings through which the bolts pass provide passages through which thecontents of the vat or vessel leak. It is also common to mount themanhole-door upon pivots or hinges, so that it may be swung inwardly foropening the manhole and outwardly for closing the same. The hinges orpivots on which the door is mounted, however, in the old constructionsform rough or uneven places on the interior of the tank and providelodgment for dirt and filth, which tends to'breeddisease bacteria and torender the vats difficult to clean and really unfit for further use.

The object of my invention is to so construct and secure in place therings constituting the metallic frame surrounding the manhole that thebolts by means of which said rings are secured in place are locatedoutside the line of connection between the door and the vat, so thataccess to said bolts and to the openings through which they pass-is cutoff from the liquid contained in the vat.

A further object of the invention is to construct and arrange the hinge'on which the door is mounted for pivotal movement at a point removedfrom the interior of the vat or vessel, so that the contents of thevessel when filled are cut off from said hinge.

Other objects and advantages of the invention will hereinafter appear,and the novel features thereof will be set forth in the claims.

In the drawings forming a part of this specimanhole 1.

fication, Figure 1 is a face view of the manhole portion of a vat orstorage vessel, showing my improvement. Fig. 2 is a sectional view ofthe same on the line 2 2 of Fig. 1. Fig. 3 is a section on the line 3 3of Fig. 1, and Fig. 4 is a detail view of the hinge.

The manhole 1 in the vat or vessel 2 has been shown as elliptical inshape; butit is obvious that it may be circular, rectangular, or othersuitable shape. Surrounding the manhole 1 and secured to the outersurface of the staves of which the vat or vessel 2 is made is a metallicring 3, corresponding in shape with the manhole 1 and having itsinneredges fiush with the Walls of said manhole. On the inside of the vat orvessel 2, opposite the ring 3, is a metallic ring 4, said ring 4 beingprovided with a rib or flange 5, which projects therefrom into theinterior of the vat, as clearly shown. The flange 5 is formed around theouter edge of the ring 4, and the base portion of said ring, which liesin contact with the inner surface of the vat 2, is provided with aplurality of bolt-openings, through which the securing-bolts 6 pass.These bolts extend through corresponding openings in the staves of whichthe vat or vessel 2 is made and in the ring 3. The outer ends thereofare provided with nuts 7, by means of which both the rings 3 and 4 maybe firmly and securely clamped to the body of the vat.

The door'8 is located within the vat 2 and is of a shape correspondingwith that of the Around its outeredge are formed the flanges 9 and 10,substantially parallel to each other and forming between them a grooveor channel 11, in which is adapted to fitwhen the door is in its closedposition the flange 5 on the ring 4. Seated in the groove or channel 11is a packing ring or gasket 12, against which the flange 5 bears whenthe door is closed, so as to produce a tight joint between these parts.The said door is provided with the bracing or strengthening ribs 13,which terminate at the center ofthe door in the lugs or projections 14.Said door is also provided in line with but outside of the lugs 14 withthe lugs 15. Through the lugs 14 and 15 extends a pin or bolt 16, towhich-is pivotally connected a clamping bolt 17, extending through abridge-piece 1S and having a nut 19 upon its outer end. The oppositeends of curing the door 8 firmly in its closed position,

but for the formation of a close impervious joint between the flange 5and the packingring 12, which prevents the leakage or escape of theliquid within the vat when the door is in its closed position.

The door 8 is mounted upon a hinge 20, so that when the nut 19 on theend of the locking-bolt 17 has been removed said door will be free to bemoved inwardly within the vat for the purpose of opening the manhole toprovide access to the interior of the vat. The hinge 20 is what may betermed a double hinge, being made up of the pivoted sections 21 and 22.l The section 21 is pivoted upon a pin 23, mounted in lugs orprojections 24 on the ring 4, and the section 22 is provided with a yokeor fork at the end opposite its point of connection with the section 21,the branches 25 and 26 thereof being pivoted to the bolt 16 between thelugs 1-1 and 15, as clearly shown. Now it will be observed that when thedoor 8 is in its closed position all parts of the hinge 20, on which itis mounted, are cut off from the interior of the vat. Contact betweenthe contents of the vat and said hinge is therefore prevented, and anydirt or foreign matter on the hinge is prevented from contaminating saidcontents. It will also be observed that when the door 8 is in its closedposition the bolts 6, which secure the rings 3 and 4 in place, and theopenings through which said bolts pass are cut off from the interior ofthe vat, so that there is no danger of leakage of the contents of thevat through said openings. The latter result is obtained, as will beapparent, by forming the flange 5 around the outer instead of around theinner edge of the ring 4 and extending the securingbolts for the ring 4through the base thereof.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is- I 1. In a storage vessel having a manholeor other opening therein, the combination with a metallic ring on theinside of said vessel and a door cooperating therewith to form asealing-joint, of securing means for said ring located between saidjoint and said manhole.

2. In a storage vessel having a manhole or other opening therein, thecombination with r a metallic ring on the inside of said vessel and adoor cooperating therewith to form a sealing-joint, of bolts forsecuring said ring to said vessel, the said bolts and the openingsthrough which they pass being located between said joint and saidmanhole.

3. In a storage vessel having a manhole or other opening therein, thecombination of a ring secured to the inner surface of said vessel andhaving an inwardly-extending flange around its outer edge andaninwardly-opening door having a groove or channel therein for receivingsaid flange, the securing means for said ring being cut off from accessto the interior of the vessel by said flange and door.

4. In a storage vessel having a manhole or other opening therein, thecombination of a ring on the inside of the vessel comprising a base andan inwardlyextendin g flange around the outer edge thereof, aninwardly-opening door having a groove or channel therein for receivingsaid flange, and securing devices for said ring extending throughopenings in "said base.

5. Inastorage vessel having a manhole or other. opening therein, thecombination of a ring on the inner surface of the vessel comprising abase and an inwardly-extending flange around the outer edge thereof, adoor having flanges around the outer edge thereof forming a groove orchannel adapted to receive the flange on said ring, a packing ring orgasket in said groove or channel, and securing-bolts for said ringextending through the base thereof.

6. In a storage vessel having a manhole or other opening therein, thecombination with a metallic ring secured to the inner surface of thevessel and a door cooperatin g with said ring to form a sealing-joint,of a hinge on which said door is mounted located outside said joint whenthe door is in its closed position.

7. In a storage vessel having a manhole or other opening therein, thecombination with a metallic ring secured to the inner surface of thevessel and a door cooperating with said ring for closing the manhole, ofa double hinge on which said door is mounted, the same comprising twosections pivoted to each other and, respectively, to said ring and tosaid door.

8. In a storage vessel having a manhole or other opening therein, thecombination of a ring secured to the inner surface of the vessel aroundsaid opening and having lugs or projections thereon, a door cooperatingwith said ring for closing said manhole having a plurality of lugsthereon, a pin extending through said lugs, and a double hinge on whichsaid 'door is mounted comprising two sections pivoted to each other and,respectively, to the lugs on said ring and to said pin.
